Depending on the vehicle's equipment, the radar
sensors are integrated behind the bumpers
and/or behind the Mercedes star. The ultrasonic
sensors are located in the front and rear bump‐
ers. Keep these parts free of dirt, ice and slush
(/ page 363). The sensors must not be cov‐
ered, for example by bicycle racks, overhanging
loads, stickers, foil or foils to protect against
stone chipping. Additional license plate brackets
can likewise impair the function of the ultrasonic
sensors. In the event of damage to the bumpers
or radiator grill, or following a collision impacting
the bumpers or radiator grill, have the function
of the sensors checked at a qualified specialist
workshop. If the sensors are damaged, some
driving systems and driving safety systems may
no longer function properly.

Functions of ABS (Anti-lock Braking System)
ABS regulates the brake pressure in critical driv‐
ing situations:
R
During braking, e.g. at full brake application
or insufficient tire traction, the wheels are
prevented from locking.
R
Vehicle steerability while braking is ensured.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can serve as a reminder to take
extra care while driving.
System limits
R
ABS is active from speeds of approx. 3 mph
(5 km/h).
R
ABS may be impaired or may not function if a
malfunction has occurred and the yel‐
low ! ABS warning lamp lights up contin‐
